The registered nurse is discussing care of an infant diagnosed with a patent ductus arteriosus (PDA) with a nursing student. The registered nurse determines that the nursing student needs further teaching regarding a PDA when the student states that which circulatory change is a characteristic of this disorder?
This shunting allows oxygenated and unoxygenated blood to mix.
Blood is shunted to the right side of the heart.
This shunting results in increased pulmonary blood flow.
Blood is shunted to the left side of the heart.
The Correct Answer is D
A. "This shunting allows oxygenated and unoxygenated blood to mix."
Explanation: This statement is correct. In PDA, the shunting of blood between the aorta and pulmonary artery allows oxygenated and unoxygenated blood to mix, leading to decreased oxygen saturation in the systemic circulation.
B. "Blood is shunted to the right side of the heart."
Explanation: This statement is correct. In PDA, blood is shunted from the left side of the heart (aorta) to the right side of the heart (pulmonary artery).
C. "This shunting results in increased pulmonary blood flow."
Explanation: This statement is correct. PDA leads to increased pulmonary blood flow as a result of the shunting of blood from the aorta to the pulmonary artery.
D. "Blood is shunted to the left side of the heart."
Explanation:
A patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that normally closes shortly after birth, remains open. In PDA, blood is shunted from the aorta (left side of the heart) to the pulmonary artery (right side of the heart), resulting in increased pulmonary blood flow. Therefore, the correct statement is that "Blood is shunted to the right side of the heart."

Correct Answer is A
Explanation
A. "Has the child had any difficulty swallowing food?"
Explanation:
One potential long-term effect of cleft palate repair is difficulty with swallowing or feeding. Cleft palate repair aims to improve the child's ability to eat and speak, but some children may continue to face challenges with swallowing or have a history of difficulty feeding.
B. "Does the child play with an imaginary friend?"
Explanation: Imaginary play is not specifically related to the long-term effects of cleft palate repair. This question does not provide information about the physical outcomes of the surgical repair.
C. "Does the child respond when called by name?"
Explanation: Responsiveness to being called by name is a general developmental question but does not specifically address the long-term effects of cleft palate repair.
D. "Was the child recently treated for pneumonia?"
Explanation: While respiratory issues can be associated with cleft palate, this question focuses on a recent event rather than the long-term effects. Asking about difficulty swallowing or feeding may provide more information about ongoing concerns related to the cleft palate repair.
Correct Answer is D
Explanation
A. "Carry a water bottle with me because I drink a lot of water."
Explanation: Staying hydrated is crucial, especially for individuals with paralysis who may be prone to urinary issues. Carrying a water bottle is a good practice to maintain adequate hydration.
B. "Use a suppository every night to have a bowel movement."
Explanation: Using a suppository for regular bowel movements is a positive self-care behavior. It helps manage bowel care, which is important for individuals with paralysis.
C. "I do wheelchair exercises while watching TV."
Explanation: Engaging in wheelchair exercises to maintain mobility is a positive self-care behavior. It helps prevent complications related to being sedentary, such as muscle atrophy.
D. "I only need to catheterize myself twice every day."
Explanation: This statement may indicate a need for further teaching. Individuals with paralysis, especially due to conditions like spina bifida, often have neurogenic bladder dysfunction. They typically require more frequent catheterization, potentially every 4-6 hours, to ensure adequate bladder emptying and reduce the risk of complications like urinary tract infections (UTIs) or bladder infections.
